Explore our precision-engineered, high-performance structural steel and roofing sheets, fabricated specifically to combat high salinity and thermal fluctuations across Turkish industrial zones.
Turkey represents one of the world's most dynamic industrial hubs, strategically bridging Europe, Asia, and the Middle East. With an intense focus on modernizing infrastructure, accelerating seismic-resistant residential construction, and expanding massive photovoltaic energy networks, procurement managers require structural metals that exceed traditional performance metrics. This is where Galvalume Steel Sheets (55% Aluminum, 43.4% Zinc, and 1.6% Silicon alloy coated steel) play a critical role.
A vast portion of Turkey's industrial production resides in coastal regions—from the Marmara basin (Gebze, Kocaeli) to the Aegean coastline (Izmir) and Mediterranean ports (Mersin, Iskenderun). The combination of marine humidity, elevated atmospheric salinity, and industrial sulfur dioxide emission accelerates the degradation of standard galvanized steel (GI).
Engineers are increasingly shifting specifications to Galvalume (GL). Thanks to the microscopic phase distribution of its barrier coating, Galvalume yields a corrosion resistance rate 3 to 6 times greater than conventional galvanized steel of equal coating thickness, making it ideal for the highly aggressive humid microclimates of Turkish industrial ports.
Turkey’s National Energy Plan aims to scale up solar energy generation capacities significantly. Constructing reliable solar trackers and mounting brackets across solar farms in Central Anatolia (such as Konya and Ankara) demands materials with superior longevity and high reflectivity. Galvalume steel sheets offer high thermal reflectivity (exceeding 65%), helping panels stay cooler and operate at peak thermodynamic efficiency, whilst guaranteeing a maintenance-free installation lifetime exceeding 25 years.
Understanding the chemical and mechanical variances is essential for engineering procurement. The table below details why AluZinc / Galvalume is the optimal technological choice over standard GI for Turkish infrastructure.
| Performance Characteristic | Galvalume Steel Sheets (55% Al-Zn) | Hot-Dip Galvanized Sheets (99% Zinc) | Impact on Turkey Local Engineering Projects |
|---|---|---|---|
| Atmospheric Corrosion Resistance | Excellent; 3 to 6 times longer lifespan under high salinity & coastal sulfur environments. | Moderate; sacrifices quickly in moist, high-chloride coastal zones. | Crucial for coastal developments in Kocaeli, Izmir, and Mersin. |
| Thermal Reflectivity | High reflectivity (>65%); reduces cooling load on building envelopes. | Low reflectivity; absorbs more ambient thermal energy. | Lowers HVAC energy costs for factories in hot Anatolian summers. |
| High-Temperature Resistance | Maintains structure up to 315°C without discoloration or scaling. | Begins peeling and oxidizing at temperatures exceeding 200°C. | Highly recommended for industrial chimneys, exhaust shields, and warehouses. |
| Edge Cut Protection | Good; galvanic zinc protection combined with barrier properties. | Excellent; sacrificial zinc protection over cut edges. | Requires careful handling during onsite profiling and cutting. |

Importing structural metal elements into Turkey requires meeting rigorous quality and structural standards to guarantee structural reliability under seismic and climatic loads. Ningbo Puppet Steel Co., Ltd. strictly manufactures in accordance with key global standards, facilitating rapid compliance mapping for Turkish customs and engineering consultants.
All our Galvalume and galvanized products comply with the European Standard EN 10346 (continuously hot-dip coated steel flat products). CE mark validation guarantees access to Turkish municipal construction bids.
For industrial solar projects requiring high yield strength grades (such as Grade 50 or Grade 80 / G550), our materials strictly follow ASTM A792 guidelines for AluZinc coated steels, ensuring reliable tension limits.
We provide complete material test certs (MTC EN 10204 3.1) and alloy composition analysis, smoothing validation with the Turkish Standards Institution (TSE) for government and private tenders.

The global steel landscape is progressing toward green metallurgy and optimized coatings. Puppet Steel is aligning our technological roadmap to these trends, directly benefiting the Turkish manufacturing sector:
Traditional architectural structures rely heavily on thicker gauges, adding massive deadweight. We are transitioning supply lines to offer super-thin, highly ductile G550 grade Galvalume (down to 0.15mm), reducing raw material volume by up to 20% while maintaining equivalent load-bearing properties for light steel framing (Hafif Çelik Yapı) in Turkey.
Our production integrates Cr-free (chromium-free) passivation treatments to comply with strict European REACH environmental directives, ensuring safety during panel handling and compliance for food processing cold rooms and agricultural structures across Turkey.
Based in Ningbo, a major deep-water port city, Puppet Steel guarantees smooth international logistics and efficient customs documentation processing. We work directly with major ocean shipping lines to ensure your steel cargo arrives undamaged and on time.
Direct access to Ningbo-Zhoushan Port, the world's busiest container hub. Ensures daily vessel departures and minimal domestic transit delays for raw material shipments.
We arrange sea transit directly to primary Turkish shipping terminals: Ambarli (Istanbul), Aliaga (Izmir), Evyap Port (Kocaeli), and Mersin, with average sea transits ranging from 25 to 35 days.
Coils are tightly wrapped in anti-moisture paper, protected by steel rings and outer plastic shields, then reinforced with timber/steel blocks in-container to prevent shift damage during heavy seas.
Detailed technical and commercial inquiries answered by our veteran metallurgy engineers.
A1: Galvalume is highly durable in outdoor atmospheric conditions, but it is not recommended for structures housing livestock. Animal waste generates high concentrations of ammonia, which chemically attacks the aluminum-zinc coating, resulting in accelerated corrosion. In these cases, heavy galvanized sheets with specialized organic coatings are preferred.
A2: For solar tracking systems and structural components within 5km of the Mediterranean or Aegean Sea, we advise using a minimum coating mass of AZ150 (150 grams per square meter, double-sided). For inland arid zones such as Konya or Kayseri, AZ120 is sufficient to provide a 25+ year lifecycle.
A3: Our manufacturing facilities utilize automatic thickness control (AGC) systems on the cold-rolling mills. Combined with continuous online x-ray coating weight measuring systems, we guarantee thickness tolerances within +/-0.02mm, adhering strictly to EN 10143 standards.
A4: Yes, Galvalume steel can be welded using standard resistance and arc welding methods. However, due to the zinc and aluminum coating, welding parameters must be closely adjusted, and proper ventilation is required to manage fumes. The welded areas must be coated with zinc-rich paint immediately to prevent local corrosion.
A5: Typical production time for customized sizes, special slit widths, or bent profiles is 15 to 25 days from contract validation. Ocean shipping from Ningbo Port to Istanbul/Mersin adds approximately 30 days.
A6: Galvalume has exceptional thermal stability. It reflects more than 65% of solar radiation, reducing interior warehouse temperatures by up to 4°C to 6°C compared to galvanized and uncoated roofs. It can withstand sustained exposure up to 315°C without discoloration.
A7: No. Direct contact between Galvalume and copper or lead causes galvanic corrosion due to the difference in electrochemical potential. Runoff water from copper pipes or flashing onto Galvalume surfaces will also accelerate degradation. Always use compatible non-metallic washers or stainless-steel fasteners.
A8: AFP treatment is a thin organic coating applied over the AluZinc surface. It prevents oil and sweat stains from showing during handling, enhances profiling lubrication, and offers temporary protection against black rust during transit and storage.
